Correct Option: B

Independence coincided with the partition of India, in which the British Indian Empire was divided along religious lines into two new states—the Dominion of India (later the Republic of India) and the Dominion of Pakistan (later the Islamic Republic of Pakistan and Bangladesh); the partition was accompanied by violent communal riots. The Dominion of India, also known as the Union of India, was a predecessor to modern-day India and an independent state that existed between 15 August 1947 and 26 January 1950. Although it was transformed into the Republic of India by promulgation of the Constitution of India on 26 January 1950, the term “Union of India” (or simply “the Union”) is still used by the Indian judicial system.
